Sensor Product Technology-Industrial Grade Accelerometer Revealed

Sensors are the first point of contact for obtaining accurate and effective data; they play an important role in converting raw physical quantities into data that is easy to measure and calculate. With the rapid development of various engineering technologies such as electricity, ships, aviation, and aerospace, more accurate dynamic data is increasingly needed for related application scenarios. High-energy power devices such as aircraft engines, gas turbines, and steam engines have put forward more stringent requirements for industrial-grade sensors. Among the many sensors, the author takes industrial-grade accelerometers as an example, combines applications and related product data, and simply shares some experiences and experiences.

What is an accelerometer?

An accelerometer, also known as an accelerometer, is a sensing device used to measure acceleration. The device measures the inertial force it experiences during acceleration and uses Newton's second law to derive the acceleration value. Based on the sensing mechanism, it can be divided into piezoelectric, capacitive, inductive, strain gauge, piezoresistive, etc.

Automobile Ride Comfort Test Application

The acceleration sensor is installed on the vehicle seat to measure the vibration acceleration process in the three axes of XYZ, which is used to evaluate the road test of the vehicle's driving smoothness.

Industrial grade accelerometer

When choosing an accelerometer, users mostly base their choice on the accelerometer range and the actual application. For example, for tilt angle measurement, a range of ±1.5g is sufficient. A ±2g accelerometer can be used in most consumer electronics and commercial applications. However, for measurement applications such as emergency stops, drastic changes in multiple directions, and high vibration intensity, an accelerometer with a range of at least ±10g or more should be selected.

In many industrial application scenarios, shock and vibration need to be monitored and measured. Due to the large fluctuation range of the application environment temperature, the range, sensitivity and accuracy of the accelerometer are required to be high. Conventional acceleration sensors are completely incapable of such harsh working environments. Based on this, industrial-grade acceleration sensors came into being. They are fully capable of maintaining high-reliability continuous measurement and stable output in such harsh application environments.
